In window and door frames as usually constructed, difliculty has been experienced in excluding the entrance of moisture and cold air, particularly after shrinkage through the joints between the head and side casings and between the head casing and the water drip which ordinarily surniounts the head casing. The opening'of these joints, usually resulting from shrinkage of the wood, not only allows moisture to enter the window frame, but permits the passage of currents of cold air into and around the window frame.

The primary object therefore of my invention is to provide a simple means in the joint between the head and side casing and between the head casing and the water drip which without adding materially to the expense of the frame, will effectually prevent moisture or cold air from entering these joints following an opening or enlargement thereof due to shrinkage of the wood and penetrating the space in the rear of the casing and the.

walls of the building; It also insures a good tight joint at this point even though there may be practically no contraction of the wood.

A further object is to provide a means for excluding moisture which will require no fitting or adjustment when a casing and frame are assembled in the building.

from the following detailed description.

In the accompanying drawings forming a part of this invention Figure 1 1s a vertical sectional view through a window frame embodying my in-' vention Figure 2 is a perspective view showing a bets 10 and 11 extending longitudinally thereof and provided in the opposite diagonal corners of the casing; The side casing has a rabbet 12formed in the upper end'thereof and the rib 13 at the rear of this rabbet is adapted to fit into the rabbetIO in the lower edge of the head casing 8 and form a waterproof and substantially windproof joint therewith. The side casingfon the opposite side of the window is formed in a similar way and when the casings are .assembled on'the frame these joints will be closed and it will be practically impossiblefor wind, rain or melting snow to pass through t'he'joints into and perhaps throughthe wall. The water "drip 9 has a rabbet l l' formed in its lower surface with a rib 15 that is adapted to enter the rabbet 11 in the upper edge of the head casing 8, the water drip projecting beyond the face of the casing as usual in structures of this kind. Then the head casing and the water drip are assembled, the joint will be broken between them, making a tortuous passage and sealing it against the entrance of wind or moisture between the water drip and the upper edge of the casing.

- The rabbets may be of anysultable depth but I have found one eighth of an inch sufficient to maintain broken joints even though there may be a considerableshrinkage in the 7 wood, but of course the depth of the rabbets Other objects of the invention will appear may be varied according to the character of the wood of which thecasing is composed.

By having corresponding rabbe'ts formed in the upper and lower edges of the head casing and diagonally therein, it is unnecessary when the frame is set in the building to.

adjust the head casing in any particular way, either face may be outermost, and the water drip will fit the upper edge and the lower edge of the casing will fit the upper ends of the side casing regardless of which face of the head casing may be exposed. This feature of the device facilitates the assembling of the frame and casing.

I have shown the invention as applied to the casing of a window frame but do not confine myself to such application as it is equally important to prevent the passage of moisture and cold air through the joints in the casing of a door frame.

By extending the rabbet the full length of the head casing on the under side as shown, it can be used to fit into the upper end of a screen or storm sash and hold it in place without the necessity of hardware, and furthermore the rabbet in the upper end of the side casing is a more simple, less expensive operation than it would be to make two rabbets and form a tongue in the center, as when a frame is being cut down or re-worked. The formation of these rabbets in the head and side casings therefore not only provides an efiicient means for excluding moisture and cold air from the building around the window frame, but also facilitates the use of storm sash or screens in connection with the window, all without adding materially to the expense of production of the head and side casings.

I claim as my invention: A window or doorframe having a head casing with rabbets in the upper and lower edges thereof, a water drip having a rabbeted under surface to fit the rabbeted upper edge of said head casing and side casings having rabbeted upper ends to fit the rabbeted lower-edge of said head casing, the rabbetsof the head casing being in the diagonally opposite upper and lower edges Whereby eitherface of said casing may be exposed in setting the frame. Y

In witness whereof, I have hereunto set my hand this 19th day of September, 1929;

FRED G. ANDERSEN.
